Abstract: In a high-speed packet multiplex communication network including a transmission line with a predetermined bandwidth and accommodating a plurality of information sources, the sources having various packet delivery rates over a range of between a peak rate and a lower rate than an average rate and demanding various transport performances, the sources are preliminarily classified into a plurality of types according to transport performances required and different transmission priorities are assigned to the different types, respectively. Bandwidths of sources of first priority and second priority are determined ones corresponding to the peak rate and the average rate, respectively. A virtual bandwidth may be calculated for the second priority source as a value between the peak and average rates. In response to connection requests from the sources, each of the connection requests is admitted when a bandwidth defined by the priority of each source is accepted in a residual bandwidth of the predetermined bandwidth, and the packets from the source of the first priority are preferentially transmitted to the transmission line, packets of the second priority source are transmitted when packets of the first priority source are absent. Thus, high bandwidth efficiency is insured while the high transport performance of the first priority source is maintained.

Title: Countercurrent separation process and apparatus
Inventor: SHINNAR REUEL
IPC: B01D11/04
Filed: 1990-06-06
Abstract: A multistage countercurrent separation apparatus and method is described. Each stage includes a mixer zone (M) and a settler zone (S), both of which have temperature control means to achieve a first temperature in the mixer zone and a seoond temperature in the settler zone. Solvents used in the process are selected so that they have at least one immiscibility transition temperature such that they form a single homogeneous phase at said first temperature and two heterogeneous phases at said second temperature. By carrying out the process, a solute or solutes introduced into the system may appropriately be efficiently concentrated or separated with minimal agitation. Furthermore, because emulsification by rapid agitation is avoided, the homogeneous phase quickly coalesces upon passing into the heterogeous phase, thereby increasing the throughput which may be achieved by the extraction process.

Abstract: A catheter assembly is provided with a needle guard (34) that slides along the needle to shield the distal tip of the needle (20) after the needle is withdrawn from a patient. The needle passes through an aperture (38) at the distal end of the needle guard. To prevent the backflow of blood through the aperture and into the needle guard, a gasket (60) is formed in the aperture about the needle. The gasket is formed with the needle in place by filling the aperture around the needle with adhesive. After the adhesive has substantially cured but before the adhesive has tightly bonded to the needle the needle guard is moved along the needle to prevent bonding of the adhesive to the needle. The needle guard will thereafter slide along the needle with the needle passing through the formed-in-place gasket.

Abstract: 2.1. In a spiral charger for supercharging an internal-combustion engine, an eccentric drive having a drive device and a guide device is provided. The latter are connected to one another in the manner of a double crank parallelogram, for example via a toothed belt. To compensate for different eccentric distances, the existing rotating mass (the displacement mass of the spiral charger) is supported softly with respect to the guide device in the region of a bearing arrangement. In a known eccentric drive, the bearing arrangement has a rubber-elastic compensating element between a bearing ring and a bearing eye. The said compensating element is highly subject to wear. In addition, heat dissipation is a problem. The new eccentric drive is intended to avoid the said disadvantages. 2.2. In one embodiment the bearing arrangement is connected via a sprung connecting element to a bearing point on the circumference of the rotating mass. In addition, a sliding fit of the bearing arrangement with respect to the rotating mass is possible. Furthermore, a rubber layer, which is vulcanised on in each case, can be provided in a flat gap between the bearing arrangement and the rotating mass. 2.3. Supercharging of internal-combustion engines. <IMAGE>

Abstract: An edge enhancement method and apparatus for dot matrix devices are disclosed wherein a group of gradient mask matrices (174) are applied to a current matrix (172), wherein a TBAP (To Be Adjusted Pixel) is surrounded by neighboring pixels, to determine if the TBAP is at a location where a change of brightness occurs. From this matrix operation, a conclusion is derived as to the existence or non-existence of an edge and the direction of the brightness change. The current matrix (172) and a predetermined number of previously evaluated and yet to be evaluated pixels (366, 367) are then compared to a set of reference bit patterns which depict possible segment changes to be corrected. If the result indicates that the TBAP is on an edge of a changing edge segment, a corresponding code will be generated to modify the TBAP to enhance the smoothness of a segment transition. In the case of an electrophotographic printing machine, the specific code will change either the location or the size of the TBAP; whereas in the case of a monochrome screen display, the specific code will change the intensity of the TBAP
